In recent years, news reports have often been reported that "Some Star died of cancer". Many readers also left messages and asked questions, saying that their relatives and friends around them were also diagnosed with cancer. Is there really more and more cancers? We speak with data.
At the beginning of this year, the team of director of the National Cancer Center Hjie Academician published a China Cancer Data Report. The report shows that in 2016, the number of cancers in my country was .06 million . The total incidence rate of men remained stable, and the average annual growth of women was 2.3%. Due to the increase in the population base, the overall number of cancers in is still increasing.
. According to the forecast of WHO IARC, the number of cancer patients around the world will double in the next 50 years to 34 million.
1. Why are people nowadays so prone to cancer?
We all know that many cancers are related to genetics, but the significant increase in cancer patients is not just the reason for genetics.
Cancer is closely related to age. Data shows that most cancer patients are the elderly, and the risk of cancer among the elderly over 70 years old is more than 100 times that of young people aged 20 years old! As the aging speed accelerates, the proportion of middle-aged and elderly patients continues to increase.
In addition, many cancer types have a tendency to "rejuvenate", such as colorectal cancer, breast cancer , gastric cancer , etc.
Factors affecting cancer include immunodeficiency , infection, ionizing radiation, environmental pollution, chronic inflammation, bad living habits, etc. Among them, bad living habits are becoming more and more common in modern life , such as smoking, drinking, staying up late, lack of exercise, high-fat diet , etc.
Harvard University published in Gastroenterology shows that more than 50% of the common digestive tract cancers in my country are related to lifestyles such as smoking, drinking, lack of exercise, overweight, insufficient intake of vegetables and fruits, and unhealthy diet. It needs to be taken seriously.
With the improvement of medical level, the medical services and statistical systems are becoming more and more perfect. The cancer diagnosis rate is higher, and the awareness rate is also higher. In addition, the increased diagnosis level has greatly increased the chance of cancer being detected in the early stages.
2. Prevention of cancer starts with diet. Don’t be greedy for these 4 foods in supermarkets.
The above research points out that if you continue to have a bad diet and lifestyle and do not prevent it, it is expected that China will add 2.3 million new patients with digestive tract tumors in 2031. The key measure to prevent digestive tract tumors is to "control your mouth". You can eat the following four types of foods in moderation, and don't be greedy.
study found that each person consumes 50g of processed meat every day, and the risk of colorectal cancer increases by 18%. The reason why processed meat causes cancer is related to the nitrite . After nitrosal enters the human body, it can bind to secondary amine of protein , producing strong carcinogen nitrosamine .
However, there is no need to completely refuse processed meat. It is okay to eat it once or twice occasionally. It is recommended to purchase it through formal channels, and give priority to low-fat, low-salt, non-smoked roasted ones.
Red meat belongs to the 2A carcinogen. Research has found that intake of too much red meat will increase the level of antibodies in the body, trigger inflammation, and increase the risk of cancer. In addition, the content of trans fatty acid in red meat is higher than that of white meat, and long-term large intake of trans fatty acids is closely related to diabetes , cardiovascular and cerebrovascular diseases , cancer, etc.
Eat meat healthily. First of all, you must control the intake. Intake of poultry and livestock every day 50-75g. The cooking method is mainly cooked and try to avoid frying and roasting.
Chinese salted fish are listed as a class of carcinogen. epidemiological shows that it is related to the high incidence of nasopharyngeal carcinoma of in southern my country. Research believes that Chinese salted fish uses high concentrations of salt during the production process, which will produce nitrosamine compounds such as nitrosyldimethylamine.
Therefore, Chinese salted fish can only be eaten occasionally and try to eat as little as possible.
, pickled foods, due to the special nature of the production process, may contain a certain amount of nitrite, or even nitrosamine. Take kimchi as an example. If you want to reduce the risk of consumption, it is recommended to eat after pickling for 1 month. At this time, the nitrite content is significantly reduced.
In addition, it is best to choose carrot , radish and other root vegetables for pickled kimchi, because leafy vegetables are more likely to produce nitrite.
3. How to detect cancer as soon as possible? Give you the method
Academician He Jie pointed out that in order to reduce the incidence and mortality of cancer, Early intervention in is one of the important means. There are different screening methods for various types of cancer. Xiaojiu gave a brief summary for your reference.
Lung cancer : Low-dose spiral CT (LDCT), high-risk populations are screened once a year;
gastric cancer : gastroscopy , Helicobacter pylori detection, pepsinogen detection, gastrin detection, etc. High-risk populations should undergo a gastroscopy. If there is any abnormality, they will do it once a year thereafter; If there is no abnormality, do it every 2 to 3 years thereafter;
Esophageal cancer : Endoscopy, if there is any abnormality, do it every year thereafter; if there is no abnormality, do it every 2 to 3 years thereafter;
Colorectal cancer : Colonoscopy , fecal occult blood test, tumor marker test, gene test , it is recommended that high-risk people aged 40 to 75 have colorectal cancer screening ;
breast cancer : breast ultrasound and breast X-ray, it is recommended that high-risk people undergo breast ultrasound combined with breast X-ray; if it is a general risk group, you can only perform breast ultrasound examination ;
liver cancer : Serum alpha-fetoprotein test and abdominal ultrasound examination. People at high risk of liver cancer should undergo serum alpha-fetoprotein test once every six months, combined with abdominal ultrasound examination;
Although the number of cancer cases and deaths is still on the rise, we do not need to panic. As long as we improve prevention awareness, take precautions, develop healthy living habits, and conduct regular physical examinations, we can reduce the risk of cancer to a certain extent. Have you learned it?
